The data tells us that most car accidents occur between 4 and 8 p.m. each day, so take good care out there. If you do get into an accident, your vehicle will most likely need diagnostic scanning.
You might say that today’s vehicles are essentially computers on wheels. From advanced driver assistance systems (ADAS) to airbag modules and electronic stability control, our cars rely heavily on interconnected electronic systems to keep passengers safe and perform optimally. When a collision occurs, these systems can be affected even if there’s no visible damage to their components. Let’s take a deep dive into pre and post diagnostic scanning and talk about whether you need it.
Understanding Pre-Repair Scans
Pre-repair diagnostic scanning serves as a comprehensive health check for your vehicle’s electronic systems before any repair work begins. Using specialized diagnostic tools, technicians can identify which systems were affected by the collision and document existing issues. This initial scan helps create an accurate repair plan and ensures that all collision-related problems are addressed, not just the visible damage.
The Importance of Post-Repair Scanning
Post-repair scanning is equally important. After repairs are completed, technicians perform another diagnostic scan to verify that all systems are functioning correctly and no new issues were introduced during the repair process. This final scan also confirms that all safety systems have been properly calibrated and reset, making sure your vehicle is safe to return to the road.
Do You Really Need These Scans?
The answer is almost always yes, especially if your vehicle was manufactured in the last decade. Even minor fender benders can trigger fault codes or disrupt calibration in various systems. For example, a bumper replacement might require recalibration of parking sensors or blind-spot monitoring systems. Without proper scanning, these issues could go unnoticed and potentially compromise your safety.
Industry Standards and Insurance
Many vehicle manufacturers now require pre and post-repair scanning as part of their certified repair procedures. Insurance companies are increasingly recognizing the importance of these scans and including them in coverage, though policies vary by provider and circumstances. No matter what you decide, it’s definitely important to get your car in as soon as possible after an accident.
Common Issues Detected Through Scanning
- Misaligned sensors affecting emergency braking systems
- Compromised airbag functionality
- Steering angle sensor miscalibration
- Disabled blind spot monitoring
- Battery system faults
- Communication errors between vehicle modules
Choosing the Right Repair Shop
When choosing a collision repair shop, ask about their scanning capabilities and protocols. Quality shops will have up-to-date scanning equipment and technicians trained to interpret the results. They should also provide documentation of both pre and post-repair scans, including any fault codes found and corrective actions taken.
The Bottom Line
While diagnostic scanning may add to the initial repair cost, it’s an investment in your safety and your vehicle’s long-term performance. These days, vehicles are too complex to rely solely on visual inspections and mechanical repairs. Proper diagnostic scanning confirms that all collision-related issues are identified and addressed, giving you peace of mind when you get back behind the wheel.
